A detailed theoretical investigation of the large amplitude motions in the S, excited
electronic state of formic acid (HCOOH) was done. This study focussed on the the S, «-
So electronic band system of formic acid (HCOOH). ...

We have calculated the equation of state and the various
thermodynamic properties of monatomic fcc crystals by minimizing the
Helmholtz free energy derived in the high temperature limit for the
quasiharmonic theory, QH, ...
